On September 13, 2026, at 5:00 PM, global oil prices saw a significant downturn. The price of West Texas Intermediate (WTI) crude oil fell to $99.99 per barrel, a decrease of $2.49 or 2.43% from the previous session. Earlier, WTI had opened at $103.97 per barrel and closed the previous session at $102.48 per barrel.

Similarly, Brent crude oil was priced at $104.47 per barrel, down by $3.16 or 2.49%. It had opened the session at $108.95 per barrel and closed the previous day at $107.63 per barrel.

The decline in oil prices is attributed to several factors, including efforts by some Middle Eastern countries to negotiate a temporary agreement with Iran to ensure the smooth transportation of goods through the Strait of Hormuz. The Vietnamese Ministry of Industry and Trade noted that the oil market is currently influenced by escalating tensions between the U.S. and Iran, attacks by Houthi forces on Saudi Arabian oil facilities, and ongoing peace talks between Russia and Ukraine.

These geopolitical factors have led to fluctuating oil prices, with recent trends showing both increases and decreases across various products, although the overall trend has been upward.
